Black Walnut
Skyfest Poplar

The Black Walnut is a slow growing, large, straight-stemmed tree with an open crown. It produces dense, very hard, edible nuts.

Black Walnut has a deeply-furrowed, black bark. Its leaves are about 1 foot long, composed of 15 - 23 slightly stalked leaflets on a moderately stout stock which provide good dappled shade.

Despite being highly valued for its edible nuts and its shade tree aesthetics, it is rare to see this tree on the prairies.

Note: Black Walnut's roots produce a substance named juglone that is toxic to some other plants. Consider this when choosing where you plant a black walnut, as you will not be able to grow tomato, potato, cabbage, eggplant, blueberry, azalea, rhododendron, lilac, red pine and apple in the surrounding area.

Note: Plant this tree once. It will not respond well to transplanting.

Note: Although self-pollinating, planting two trees significantly improves nut production.

A top CO2 absorbing species. Experts think this tree may help climate change more than others.

Bred by Jeffries Nurseries, the Skyfest is a fast growing, tall cottonwood with excellent disease resistance and adaptability to many kinds of soil. In the fall, its leaves turn a golden yellow.

This species has an aggressive root system, making it unsuitable for planting close to buildings but very drought resistant and an excellent choice for shelterbelts.
